EXPANSIBLE BRACELET.

` Application filed January 29, 1927. Serial No. 164,503.

This invention relates to new andy useful improvements in expansible bracelets, and pertains more particularly to bracelets of this type wherein the links may be disconnected at will for the purpose of removing or adding one or more links for shortening or i lengthening' the braclet.

The primary object of the invention is to provide an improved form'of connector so as to enable the parts to be easily and quickly manipulated in disconnecting the linlrs.

In the drawings Fig. l is an inner side elevation of a fragment of a bracelet in accordance with the present invention; n

Fig. 2 is a section on line 2 2 of Fig. l and Fig. 3 is a section on line 3 3 of Fig. l.

Fig. 4 is an inner side elevation of one of the connectors. f

. In proceeding in accordance with the present invention, boxes l are provided which are ofV hollow formation and whichl have slots 2 and 3 in one ofthe ends thereof providing bars 4 therebetween. The opposite ends of the boxes are formed with slots 5 to receive the connectors 6, the latter also passing through the slots 3.0i.: an adjacent box and having hook-shaped ends 7 which embrace the bars 4 andextend through the slots 2. The opposite ends of the. connectors are turned inwardly at 8 and extend within coil springs 9. The coil springs tension the connectors and have their opposite ends abutting the ends of the boxes that have the slots 5. As shown in Fig. 4 of the drawings, the side edges of the connectors are turned inwardly or doubled upon themselves, as indicated at lO, and one of the doubled vedges is formed with a slot 11. The doubled edges l0 of the connectors not only increase the strength of the latter, but in addition the walls resultant from'the notches l1 afford increased contact for engagement. with theV linger nail ofthe operator as will now be described.

Referring to Fig. l of the drawings, it

will be seen that in disconnecting the linksr or in connecting same, the parts are initially extended to expose a notch ll, sothat vthe adjacent operator can place his linger-nail in the notch and thus hold the hook 7 spaced from the adjacent box-l.v The boxes may now be turned relative to one another so as to occupyV an angular. position so as to move the hook 7 out of the slots 2 and 3 and thus disconnect the parts. To connect the parts, the same operation is followed excepting that the hook 7 is threaded through the slots 2 and 3. i

Frein the foregoing it will be seen that the notches 1l provide an eective four-point engagement of the finger nail with the connector, so as to enable the operator to obtain a better and firmer engagement with the oonnector in 1nolding the latter with the hook 7 ont of engagement with the end wall of the adjacent box. At the same time, the doubled parts l() provide an increased guiding movment for the connectors as is apparent frein Fig. 3V wherein the slot 5 has its ends enlarged at 13 so as to provide for the reception of the doubled over parts 10.

It will further be noted that the ends of the doubledV over portions l() adjacent to the hooks 7 provide stops which prevent unlatchingof the hooks.

Having thus described my invention what I claim as newV and desire t0 secure by Letters Patent is :e

1. In an expansible bracelet, boxes having slotted ends, and spring tensioned connectors in the boxes having'hooks on one `end to detachably engage through the slot of an box, said connectors'v having their side edges turned over uponV themselves to form thickened lguides that engage the box sides throughout the lengths ot' the connectors, one ofthe turned over side edges being formed with a linger-nail receiving notch.

2. In an expansible bracelet, boxes, spring tensioned connectors inthe boxes said con- 'nectors having their side edges doubledA for the boxes, the connectore having hooks the notches Will be disposed adjacent to the on one end thereof engageable through the end of the box in which latter said connecslot at the adjacent end of the adjacent box, tor is mounted. 10

said connectors having thickened side edges j In testimony whereof have signed my 5 one of which is Jformed With a inger-nail name to this specification.
